Installation Guide

Review and understand complete
guide before beginning installation.

This guide has been prepared as sug­gested details to particular design condi­tions. Each condition has certain limitations to perform­ance, aethetics or economics. Professionals qualified to
assess this information for a specific project, should deter­mine that the selection and installation are made to their
requirements. ATAS cannot assume any responsibility
for the actual selection and/or installation of materials.
The panels, flashings and trim shown in this guide, illus­trated over solid and plumb substrate, assume that the
structure has been designed and prepared in accordance
with local building codes.

Permashake panels are simulated wood shakes
manufactured from 29 gauge G90 galvanized steel.
They are available in 6 standard colors with a Hylar 500

R

and/or Kynar 5000Rfinish. They measure 10 5/8” (nom.) x
61” (nom.) Minimum recommended roof pitch is 4:12.

PANELINSTALLATION - In environments where ice and water may dam, apply ATAShield**underlayment over entire substrate. Begin installation
over solid deck by applying ATA Shield

*

around perimeters of roof with a minimum of 36” coverage. Then apply ATA Guard*or appropriate underlay­ment over roof deck. Snap a vertical and horizontal line to square up the plane with the eave line. Start at the bottom left hand corner of the roof
plane with a full length panel. Install shingles in a left to right manner from eave to ridge. See below for stagger methods of installation. Fasten
panels to solid substrate with galvanized steel clips using a minimum of three (3) to a panel. Manufacturer recommends the use of 1” wafer head
screws.

1. When applying a re-roof application, cut back
existing shingles and drip edging to be flush with
eave and gable lines.

2. Apply A TA-Shield

**

in areas where ice & water
damming can occur. Extend underlayment over fas­cia board. Install drip edge as tight as possible
against the fascia trim. Space fasteners at maximum
of 12” o.c. Overlap eave trim a minimum of 3”.

3. Lay a full width of ATA-Guard

*

over the eave trim.
Apply butyl tape on top of drip edge and fasten
starter cleat through eave trim into substrate with
front face up as shown to right.

4. Install panel only after the gable closure is
installed (see below). Install by sliding lower flanged
edge between starter cleat and drip edge. Square
the panel in the J channel at the gable edge and fas­ten with clips and a 1” wafer head screw.

1. Install drip edge over ATA-Guard

*

2. Apply sealant along drip edge as shown to the
right. Lay the channel trim along the gable edge.
Overlap channel at a minimum of 2” to 4”.

3. Align the first shingle into the J channel and snap
a line across the roof plane. (See panel installation
section)

1. Install ATA-Shield**18” up both sides of the valley
line.

2. Install the valley pan and clip fasten through the
substrate at 24”-0” o.c.

3. Lay shingles onto the valley pan maintaining at
least 3” clearance from the valley’s center.

Underlayments: ATA-Shield** is the recommended self adhesive
underlayment for eaves, sidewall and any critical areas exposed
to ice damming and extensive water run off.
Available in 65’-8” x 39-3/8” rolls (2000 sq. ft. per roll).

Underlayments: ATA-Guard* is a polyolefin based, 100% asphalt
free, high strength reinforced roofing underlayment for use
beneath metal roofing on steep slope applications. 1000 sq. ft.
per roll at 48” wide.
